Transplantation & Cellular Therapy Meetings

A second interim analysis of the phase 3 Karmma-3 trial demonstrated significantly improved progression-free survival and overall response rates, compared with standard regimens, in patients with triple-class-exposed relapsed/refractory multiple myeloma.

Early data of the Orca-T cellular therapy showed enough positive results from patients on the therapy to move on to a phase 3 study in this patient population.

A single-center, retrospective study demonstrated high rates of chronic opioid use after autologous stem cell transplantation in patients with multiple myeloma, also leading to inferior overall survival at 6 months of follow-up.

Treatment with the chimeric antigen receptor (CAR) T-cell therapy idecabtagene vicleucel is safe and effective for patients with relapsed/refractory multiple myeloma.

Novel treatments are needed to replace transplant and prevent graft-vs-host disease in order to improve patient outcomes.

A 90-day complete response rate of 92% was observed with bispecific CAR T-cell therapy for patients with relapsed/refractory mantle cell lymphoma.

At 1 year, the GVHD-and–relapse-free survival achieved with Orca-Q was 75%, which was noted to compare favorably with prior data reported in context of myeloablative conditioning , haploidentical stem cell transplant, and posttransplant cyclophosphamide.

Ruxolitinib elicited higher responses at day 28 compared with best available therapy in most cytopenia-based subgroups and had durable responses at day 56, according to a post hoc analysis of the REACH2 trial.

According to findings presented at the 2023 Transplantation & Cellular Therapy Meetings, experts did not identify clear correlation between the pharmacokinetics and pharmacodynamics of ruxolitinib in patients with graft-vs-host-disease.

In 8 patients with various hematologic malignancies who received an allogeneic hematopoietic stem cell transplant with 7/8 non-permissive HLA mismatched donors, Orca-T led to a 100% survival rate.

In a single-institution phase 1 trial, patients with large B-cell lymphoma had high overall response rates with CD22-directed CAR T-cell therapy.

The phase 3 REACH2 trial showed that early treatment with ruxolitinib 10 mg led to higher response rates vs that seen with the best available therapy in patients with grade II-IV steroid-refractory acute graft-vs-host disease.

Looking at a retrospective analysis of data from a single-center, the use of ruxolitinib decreased non-relapse mortality and improved overall survival for patients with steroid-refractory acute graft-vs-host-disease.

Final safety and efficacy read outs of the EQUATE trial show durable clinical responses and a favorable safety profile for acute graft-vs-host disease.

Long-term outcomes did not differ among de novo late acute graft-vs-host disease and classic acute graft-vs-host disease, showing they should be treated the same way.

Regardless of prior therapies, brexucabtagene autoleucel showed a survival benefit in patients with relapsed/refractory B-cell acute lymphoblastic leukemia, according to subgroup analyses of the phase 3 ZUMA-3 trial.

While JCAR021 showed durable responses, there was a high rate of neurotoxicity when given at a dose of 7 x 106 cells/kg in patients with relapsed or refractory large B-cell lymphoma.

Risk of relapse was significantly greater for those with acute lymphoblastic leukemia who had low minimal residual disease of less than 10-4 vs those with undetectable MRD, according to results of a retrospective study.

The first-in-human phase 1 trial of ADI-001 as a treatment for patients with relapsed/refractory B-cell non-Hodgkin lymphoma led to responses and a favorable safety profile.

Findings from the phase 2 DALY II USA trial showed that the 28-day objective response rate was 78% with freshly administered zamtocabtagene autoleucel, exceeding the prespecified efficacy threshold for interim analysis.

Data comparing 4 donor types showed matched sibling donors to be preferred in patients with myelofibrosis, according to a presentation given at the 2023 Transplantation and Cellular Therapy Meeting.

JSP191 combined with fludarabine, and low-dose total body radiation demonstrated facilitation of full donor myeloid chimerism, clearing of minimal residual disease, and a well-tolerated safety profile in older patients with myelodysplastic syndrome/acute myeloid leukemia receiving non-myeloablative allogenic hematopoietic cell transplantation.

Looking at 4 CAR T-cell agents for the treatment of large B-cell lymphoma, a systematic review and analysis showed that these therapies do not appear to increase the risk of cytokine release syndrome or immune effector cell–associated neurotoxicity syndrome.

Findings from an analysis of the KarMMa study in patients with multiple myeloma signal that certain baseline characteristics are predictive of response to chimeric antigen receptor T-cell therapy.

Based on an interim analysis of a randomized phase 2 trial, use of topical ruxolitinib showed reduced body surface area of chronic graft-versus-host disease.

Continued benefit of axicabtagene ciloleucel in patients with relapse/refractory indolent non-Hodgkin lymphoma was observed in the phase 2 ZUMA-5 clinical trial.

In patients with relapsed/refractory large B-cell lymphoma, the chimeric antigen receptor T-cell agent, lisocabtagene maraleucel demonstrated durable responses.

The majority of patients treated in a phase 1 trial of belimumab used as chronic graft-vs-host-disease prophylaxis showed no evidence of the disease after 20 months of follow-up.

In a phase 2 trial, rates of steroid-refractory chronic graft versus host disease and prednisone use following treatment with abatacept after stem cell transplant were reduced.
